Modello Uno ref. U1-GM is the Made in Italy professional diving watch. It features an International orange dive dial with markers in Super-LumiNova® BGW9 white lume matching the lumed dot on the matte gray aluminium professional diver insert and a cool gray open second rail and dial trims.
Time is indicated thanks to the matte black phantom ladder hands set and the black reverse lollipop second hand with white tip. The double domed anti-reflective sapphire crystal provide the best performance in every light condition.
The solid 316 brushed stainless steel case, the screwed-in 2mm thick caseback, the 8mm diameter crown together with the high quality gaskets set provide a water resistance tested individually to 30 atm=300m=1000ft.
Timing accuracy is guaranteed by the NH35A automatic movement tuned to 21600bph with 41h power reserve and hacking second hand. It comes on an International orange TPU two piece strap, an extra black Unimatic nylon Nato strap with stainless steel brushed hardware signed Unimatic.
The caseback features the Unimatic x Grimoldi engraving and the individual progressive number. The watch is covered by a 24 months worldwide warranty and is part of a unique edition of 100 pieces.
